It is designed to fit a wide range of uses including product design, mechanical engineering, architecture and 3D printing.FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings. it is a multiplatfom (Windows, Mac and Linux), highly customizable using the Python language. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow.FreeCAD includes a modern Finite Element Analysis (FEA) tools, experimental CFD, BIM, Geodata workbenches, a Path (CNC) workbench, a robot simulation module that allows you to study robot movements and many more, and a rich collection of plugins and macros installable directly from within the application.

O Stellarium desenha um céu foto-realista tridimensional em tempo real com o OpenGL. Mostra estrelas, constelações, planetas e nebulosas e possui vários outros recursos, incluindo paisagens panorâmicas múltiplas, nevoeiro, simulação da poluição luminosa e um mecanismo de apresentações embutido.
      O Stellarium vem com um catálogo estelar com cerca de 600.000 estrelas, e é possível baixar catálogos adicionais com até 210 milhões de estrelas.
      O Stellarium tem diversas culturas estelares: veja as constelações a partir das tradições de astrónomos polinésios, inuítes, navajos, coreanos, lacotas, egípcios e chineses, bem como as constelações ocidentais tradicionais.
      Também é possível visitar outros planetas no sistema solar: veja como o céu pareceu para os astronautas da Apollo ou como os anéis de Saturno parecem a partir de Titã.

      GNU Octave is a high-level interpreted language, primarily intended for
      numerical computations. It provides capabilities for the numerical
      solution of linear and nonlinear problems, and for performing other
      numerical experiments. It also provides extensive graphics capabilities
      for data visualization and manipulation. Octave is normally used through
      its interactive command line interface, but it can also be used to write
      non-interactive programs. The Octave language is quite similar to
      Matlab so that most programs are easily portable.
    
      
      Octave has extensive tools for solving common numerical linear algebra
      problems, finding the roots of nonlinear equations, integrating ordinary
      functions, manipulating polynomials, and integrating ordinary
      differential and differential-algebraic equations. It is easily
      extensible and customizable via user-defined functions written in
      Octave's own language, or using dynamically loaded modules written in
      C++, C, Fortran, or other languages.

      Scrivano is a note-taking application aimed at those who prefer handwriting over typing. It offers a simple and easy to use interface to write down your thoughts and ideas. The app gives you an infinite vertical canvas (but limited horizontal space) without sacrificing the ability to easily export your notes in traditional printing formats (e.g. A2, A3, A4, etc...).
    
      
      Here is a summary of the most important features:
    
      
        4 different paper backgrounds to choose from: Plain, Lined, Grid or Dotted with customisable spacing and backgrounds.
        Grid Snapping: in Scrivano you can toggle the grid snapping feature so that your drawings will automatically snap to grid lines in the background. This is very useful to easily draw tables, diagrams and lines.
        Automatic filling of strokes: toggle the paint bucket in the toolbar to fill your drawing shapes and strokes.
        Stickers: save your frequently used symbols and diagrams, so you can easily drag and drop whenever you need them.
        Insert images: paste or drag and drop any image on the canvas to unleash your creativity!
        Offline saving: save your notes anywhere on your main drive, so you can manage them however you please.
        Laser: Scrivano offers a special laser tool to quickly draw over your notes. Incredibly useful when sharing your screen or presenting something!
        Annotate PDF files: You can import your PDF books, lecture slides, articles and documents to annotate them using Scrivano's built-in inking tools.
      
      
      NOTE: The flatpak version of the app runs in a sandbox environment and it can only read/write files from these folders: xdg-desktop, xdg-documents, xdg-download and xdg-pictures. If you want to circumvent this for more freedom, you can use Flatseal to override these restrictions.

All the water has disappeared from your village and it's up to you to save the day! Go on an adventure to connect the water pipes and bring water back to your village. Solve puzzles and hack your way through 15 levels of fun and challenging islands. You may discover that you'll learn some things along the way…
      Level up your coding skills by learning and practicing variables, conditionals, loops, debugging, JavaScript, math, step by step, booleans, logical sequencing, and more.
      The goal on each level is to connect all the pipes together. When near a pipe, “hack” it to rotate and connect it to other pipes. Once this is done, a door appears. To reach the door, the character may have to hack other objects like platforms and bridges to change their position and scale. This may include changing water between ice, liquid, and steam to access different areas. The water must be in liquid form for the pipes to work. If the character ever ends up in a bad place, they will be reset to the nearest surface with no bad consequences.
      Important controls:
      
        Move Mateo: Tap the mouse or trackpad on the screen
        Restart Button: Restart the level from the beginning
        Pause Button: Open options to change audio/continue level/return to level selection
        Eye Button: Click the eye in the bottom right to highlight hackable objects
        Token Button: See which code tokens you have used in the current level
        Zoom In/Out: Scroll the mouse wheel
      
      Hacking objects:
      
        Right-click on white highlighted objects to see and change their code.
        Mateo needs to be close enough to the object. Red highlight means an object is too far.
        While hacking, any text with a box can be changed by tapping the box and selecting an option.
